Surname Delaveras...We are STUCK & need HELP!

Surname Delaveras...We are STUCK & need HELP!

It was suggested to me, in the Bulgarian community, to try here, so here it goes...My husband's Mother's side has been proving to be quite the challange! His mother's maiden name was TUZ and we can get back to her Maternal GGrandfather James Delaveras (m. Mary) but no dates or places for him. However her Maternal Grandfather was also James Delaveras b. Dedagach, Bulgaria 1888 (m. Loretta Hirt-b. Connecticut). He came to New York but eventually went to Connecticut as my M-I-L's mother was born there in 1914, (we can't find any records of other children). My M-I-L has passed away & that side of the family was RARELY spoken of. We could REALLY use some help. We have tried several variants of Delaveras including breaking it into parts, but just can't find anything. THANK YOU!
